I got the same problem.
I have like 300 template for 20 different customers and now they all stopped working with the last version.
I had to correct some of them manually that were very urgent but i cant do that for the 300 template.
Im thinking about rollbacking aspose to last version i used even if this version corrected some other bug for me because it was working before!!
Can you raise the priority of this problem please? I cannot afford to wait 2 month for a fix for this..
